CONVERTIBLE DEVlCE.

SI'EOIFIGATION forming part of Letters Patent No. 742,381, dated October27, 1903.

Application filed February 2, 1903. Eerial No. 141,487. (No model.)

To all whom it may concern:

Be it known that I, WILLIAM L. BEAR, of Williamsport, county ofLycoming, and State of Pennsylvania, have invented certain new anduseful Improvements in Convertible Tools; and I do hereby declare thefollowing is a full and clear description thereof.

My invention relates mainly to metal and wood working tools.

The object of my invention is to provide a compact convertible apparatuswith the above object in View.

With these objects in view my improvements consist in the followingconstruction and combination of parts,the details of which will first befully described and featuresoi' novelty then set forth and claimed.

Figure 1 represents a side elevation and partial section of my combinedmachine. Fig. 2 is a cross-section taken on the line as as of Fig. 1looking in the direction of the arrow a. Fig. 3 is a cross-section onthe line y y of Fig. 1 looking in the direction of the arrow 1).

In the drawings, A represents a bed-plate which carries the variousfeatures of my combined tool. p

B is an anvil securely bolted to the bed A. The horn, face, and hardy ofthis anvil may be of usual construction; but the rear face or faceopposite to the horn is provided with a face 0, having a serratedsurface, and forms one of the jaws of the vise, the other jaw D (alsoserrated) being formed on the frame E.

Mounted on bed-plate A is a supplementary bed-plate F, provided withways G, along which is adapted to slide the tool-holding frame I. Uponbed A are formed bearings J, within which the feed-screw K works, theadjustment being made by revolving the wheel and the handle L in theusual way. The innor end of feed-screw K is seated in the slidingtool-frame I.

M represents balls carried in a trough of the guide-bed F and serve asantifrictionbearings for the tool-frame I.

Mounted rigidly upon tool-frame I is the frame E, whose jaw D forms onemember of Within this frame E is carried the drill or turning-spindle N,operated by the end wheel 0, (or the pulley P, where power is used.) Thedrill-bit sleeve Q is carried on the spindle N, and R is a lever pivotedat S to the frame E and having contact with the sleeve Q for the purposeof feeding the drill to its work.

As illustrated,the frames E and I are bolted to each other rigidly; butthe whole structure may be made integral, if desired. As a preferredconstruction I swivel the frame E upon the tool-frame I by means of thebolt T,which allows the frame E and its attached parts to swing in anydirection, whereby drilling may be done with my machine at differentangles. A girth-chain U is attached to the side of the frame E and is tobe used in connection with the drill for drilling in any desiredposition.

When the girth-chain U is used, the tool, the frame, or tool-holderE,carrying the drill, is preferably swung laterally on the bearing T. Onlya short section of the chain is shown; but it should be long enough topass around an object in front of the drill and back again to theopposite side of the tool-holder. Assume that it is desired to drill ahole in an object, say a pipe. The chain is passed around the pipe andits free end secured to the tool-holder E on the side opposite thatshown in the drawings. The chain simply forms an abutment which holdsthe object to be drilled against the thrust of the drill. Any otherabutment may be used instead of the girth-chain.

On the upper parts of the jaws O and D, I may attach supplemental jawsV, having tangs which take into the jaw-heads, whereby they may beremoved or replaced at will. These supplemental jaws are well adaptedfor Saddlery work.

In the adjacent faces of the anvil B and tool-holding frame I, I formundercut slots W, passing from one side to the center of the anvil andframe, as clearly shown in Figs. 1, 2-, and 3. In these slotted ways areremovably inserted the vise-jaws X and Y, the bases of said jaws beingprovided with flanges Z, which fit and slide in the slotted ways W. Thejaws X and Y may have any desirable faces. In the present instance Ihave shown them with concaved serrated jaw-faces, and I have also shownthe jaw Y smaller than the jaw X in order that they will in a measurefit within each other. These jaw-faces are well adapted for pipe-jaws orfor clamping any cylindrical object. These jaws may be removed at anytime by simply sliding them out of their recessed ways.

Mounted on the bed A or theways F is a tool-support a, carrying atool-rest Z), adapted to be adjustably clamped thereto for use inconnection with drilling or turning.

Clamped to the bed A is a forge 0, adapted for use in connection withthe other parts of the combined machine. This forge is provided with theusual air-inlet pipe and waterpot.

The whole combined machine is simple and compact, bringing convenientlytogether the several operations hereinbefore referred to into onemachine.

Vhat I claim as new, and desire to secure by Letters Patent, is

1. In a convertible machine, the combination of a bed, a standardcarrying a platen or abutment, and a second two-part swiveled standardmovable to and from the first standard, having a drill-spindle journaledin the swiveled part of the second standard.

2. In a convertible machine, the combination of a bed, a standardcarrying a platen or abutment, a second two part swiveled standardmovable to and from the first standard, having a drill-spindle journaledin the swiveled part of the second standard, and a flexible abutment orchain for holding the work against the drill of the spindle whereby thework may be drilled at different angles.

In testimony whereof I have aflixed my signature in the presence of twowitnesses.
